Verstappen has had more hits today than the Beatles.
Lap 27/44
In comes Rosberg. He takes another set of medium tyres.
Verstappen meanwhile goes very close to Perez and the Mexican goes off track.
Justin Speirs: Raikkonen doing a sterling job to make it into the points - not been an easy ride with Max Verstappen's inexperience.
Benedict Salido: ROS will get so desperate he will make another stupid move once HAM attempts to overtake him towards the end. Both Mercs will retire.
Lap 26/44
And in comes Ricciardo which will put Hamilton second for now.
Lap 26/44
A flurry of pit stops has put Hamilton back up to third. Hulkenberg emerged from the pits in fourth with Alonso behind him.
Lap 25/44
It's kicking off in the pit-lane now. Alonso leaves his pit spot and Hulkenberg is approaching on his left. They start racing side by side in the pit-lane. Crazy.
Alonso should have let Hulkenberg through but they touch wheels.

They are nowhere near getting the tyre life that they expected. Ten laps for a set of softs is what Lewis Hamilton got and he was not over-aggressive.
Lap 24/44
Massa has a five-second penalty for leaving the track, which he immediately takes.
Expect plenty of movement with more pit stops imminent.
Massa and Verstappen go past Grosjean to take 10th and 11th respectively.
Lap 23/44
Mercedes tell Rosberg he can push his medium tyre and they are switching to "Plan B". We'll find out what that plan is in good time.
Hamilton's pit stop was slow - the rear jack got stuck and the engineer needed a few tugs to release it.
"Nico, we are happy for you to push that tyre, we may go Plan B."
Lap 22/44
Where does Hamilton re-emerge? In ninth, just ahead of Gutierrez and Raikkonen.
In fact, Raikkonen seizes the moment to go past Gutierrez and into 10th.
Lap 22/44
Hamilton pits...

Very sadly it is not good news for Kevin Magnussen. He is on his way to hospital. The injury to his left ankle is clearly serious.
His team will have to start thinking about the Italian Grand Prix. Who is going to be driving for them? Can Magnussen recover in time or will they have to bring someone else in?
Lap 22/44
"We're starting to slide a lot," Hamilton says on the radio.
He'll be considering taking off those soft tyres - Rosberg is on mediums remember, so he can stay out longer.
Lap 21/44
Hamilton is less than three seconds behind Ricciardo and seven seconds behind leader Rosberg.
Still so much work to do.
Rosberg, with all the chaos behind him, has kept an impressively cool head today.
Lap 20/44
And now Raikkonen does go past Grosjean, miraculously without any contact - he's up to 12th.
Lap 20/44
Potty-mouth Raikkonen is on the radio again, swearing about a puncture he doesn't have. He feels like he's lost pressure on his front left tyre. It looks fine.
"I have a puncture again on the left front."
Lap 20/44
Raikkonen has made it a personal ambition to make contact with every car on the grid today.
The Finn goes wheel to wheel with Grosjean and they kiss rubber. Grosjean holds on to P12.
